JAR-CLOSURE.

Specification of Letters Patent.

Application filed April 13, 1908. Serial No. 426,804.

Patented Jan. 11, 1910.

To all whom "it may concern:

Be it known that I, EDGAR C. HILL, a citizen of the United States,residing at Columbus,

in the county of Franklin and State of Ohio,

have invented certain new and useful Improvements in Jar-Closures; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an improved jar closure.

The object of the invention is to provide a simply constructed cheaplymanufactured device for removably clamping an inclosure on a 'ar orother vessel and which may be quic y applied and removed and which iscapable of being used indefinitely.

In the annexed drawing forming a part of the specification in which likereference characters refer to like parts throughout the several viewsand which are for illustrative purposes only and therefore not drawn toscale, Figure 1 ,is a side elevation of the upper end of a jar with theimproved clamping device applied thereto and with parts of the jar mouthand lid broken away and the locking member in lowered position; Fig. 2is a similar view with the locking member in raised position; and i 3 isa detailperspective view of the c amping device de- 1 tached.

.is to of the collar In the embodiment illustrated, this improvedclamping device is shown ap lied to a jar A having a groove B forme inthe edge of the mouth thereof and having a rubber gasket C disposedthereon over said groove. The lid D is shown provided with an annularrib E on its lower face adapted to fit in the groove B of the jar and topress said gasket C thereinto to form an air-tight closure. This jar isalso provided with an annular collar or shoulder F made integral withthe mouth thereof to form a laterally extending shoulder G for a purposeto be described.

This improved clamping device 1 is preferably composed of a spring metalstrip of a length slig tly greater than the diameter of the jar mouthand lid and is ada ted to span the to of the jar or other vesse to whichit be applied. The end 2 of this bar is bent approximately at right anles thereto and has its terminal bent inward y to form a hook 3 foreriigagement with the under side of the jar. The other end of the bar isbent in the same direction as the end 2 but is inclined inwardly andtermi nates in a pair of laterally spaced approximately circular lugs 4between which is pivoted a lug 4 formed at the outer edge of the innerstraight portion 6 of the locking member 6. Said end of the lockingmember extends inwardly beyond the plane of the inner face of the end 4and is adapted to engage the under side or shoulder formed by the collaror shoulderF of the jar at a point diametrically oppositeto the pointengaged by the hooked end 3. This lever 5 is provided with an operatinghandle portion 7 which preferably extends outwardly with its inner facecurved to fit the upper curved surface of the jar body. These bent ends2 and 4 of the bar l'are formed of a length slightly greater than thecombined height of the collar F, thegasket, and the lid. The straightportion 1 of the bar 1 which extends across the jar is curveddownwardlyintermediate of its ends to adapt it to closely engage the lid of thejar when the lever is thrown into locking position and thereby firmlyhold the lid in air-tight contact with the jar mouth. This bar 1 beingcomposed of spring metal with its straight portion bent downwardly atthe center thereof provides for the raising and lowering of the lever 5and its inner end engagedwith the shoulder G of the jar 1 forms afulcrum for the lever.

To only temporarily hold the lid or closure upon the ar, the clam ingmember is applie in extreme raised position, when the clamping memberproper assumes the position indicated in Fig. 2. The upward swinginmovement of the locking member is limite by the outer edge 8 of itsinner portion 6 engaging with the wall 9 formed at the inner ends of thelugs 4 The clamping member may be removed as a whole from a jar bysliding it transversely therefrom with the locking member in eitherraised or lowered position.

- I claim-as my invention:

A' clamping member for jar closures comprising a resilient flat metalmember having its opposite ends bent in the same direction and theterminal of one of said ends bent inwardly to form a hook for engagingthe jar flange, the other end being longer and being inclined inwardlyand terminating in a pair of laterally spaced lugs a locking memberpivoted between the lugs of said inlowered position, the clamping memberbeing removable as a whole from the jar, with the locking member ineither raised or lowered position bysliding it transversely therefrom. y

In testimony whereoi I have hereunto set my hand in presence of twosubscribing witnesses.

EDGAR CAMPBELL HILL.
